Title: Apparatus for spreading inoculant on culture plates
IPC: C12M1/32
Filed: 1976-07-31
Abstract: 1526037 Spreading inoculant on culture plates M P J DEVELOPMENTS Ltd 13 July 1977 [31 July 1976] 32036/76 Heading C6F Apparatus for spreading a deposit of inoculum on a culture plate whereby to produce a progressively more dilute inoculant trace thereon, consists essentially of an inclined plane 1, Fig. 1, and a spreader head 10 driven by a motor 14. In operation, a culture plate, comprising a circular base and a detachable cover of slightly larger diameter, slides down the inclined plane under gravity between the vertical surfaces 4. During the descent, the cover is taken off the plate through engagement with shelves 30. The further descent, rotation and return of the uncovered plate is controlled by the relative rotation of two spaced endless belts 7 between which it is caught. When the plate reaches the trigger 8 the rotary spreader head 10 is lowered on to the surface of the plate, the plate is caused to make about two rotations with the spreader close to the periphery, and then, still rotating, to move slowly up the inclined plane until the centre of the surface of the plate reaches the spreader, thereby spreading inoculum over the whole plate surface. The spreader head is then raised away from the plate and the plate returns up the incline into engagement with the separated cover, and the plate and united cover are raised past two pawls 12 extending from the respective surfaces 4 by the upstanding extensions 11a, 11b of a pivotally actuated member 11. On retraction of the stacking extensions, the plate is lowered on to the pawls 12 which have in the meantime pivoted back to their rest position. The spreader consists of loops 17 of electrically conductive material arranged around the periphery of a circle and disposed so that the loops can be sequentially brought into contact with the surface of the culture plate as the head is rotated by motor 14. One side of each loop is straightened and disposed approximately parallel to the rotational axis. An electric current is passed through the loops between cycles to heat up the spreader to sterilize it. Preferably two spreader heads are employed.

Abstract: 666,386. Mixing appliances. DEHN, S. G. (Kinetic Mixer Co.). Dec. 19, 1949. No. 32508/49. Class 86. A method of mixing asphaltic paving compositions including aggregate and binder includes the steps of rotating a mass of the material in a substantially closed zone at a rate sufficient to form an annular rotating mass, abruptly changing the direction of motion of the central portion of said mass from a circular to a radial direction, diverting the remaining portion of said mass from the side portions of said annular mass laterally towards the centre, and causing said radially directed and laterally directed masses to superimpose and merge. In Fig. 2, a cylindrical container 14, closed at one end and having an annular flange 18 at the other end, is mounted for anticlockwise rotation within a fixed casing 6. The material is forced centrifugally into an annular mass upon the inner surface of the cylindrical wall of the container 14 and is mixed by deflectors 27, 41, 42, Fig. 4, supported from the end wall 8 of the casing 6. The central portion of the annular mass of material is diverted by the deflector 27 into a radial path and then under gravity falls back on to the container wall where it combines with the side portions of the annular mass which have been diverted laterally inwards by the deflectors 41, 42. Liquid binder may be sprayed into the mixture through a slot 59 in a pipe 58 behind the deflector 27. The container is charged by means of a hopper 44 leading to an opening in the wall 8 and is discharged by a scoop 47 which can be brought into its discharge position by means of a lever 57.

Title: Improvements relating to the suppression of froth in fermentation vats and similar vessels
IPC: B01D19/02
Filed: 1932-11-21
Abstract: <PICT:0397722/III/1> Froth is suppressed in distilling columns by causing the rising froth to entrap in a column 3 with an open lower end 4 above the level of the liquid 5, and utilizing the pressure of the entrapped air to raise a flap 10 by a bellows 9 and so prevent air escaping from the pipe 17.  Pressure is thus increased beneath the diaphragm 20 which operates a valve 22 to allow oil or molten fat to pass to a spraying device 24.  The control valve may also regulate the compressed air of an ejector device which draws up oil from a reservoir, or the air pressure may be arranged to operate a piston or diaphragm which in turn may close the circuit of a solenoid adapted to operate the oil supply valve directly or through a relay, or the air pressure may operate a diaphragm which in turn operates a valve controlling air pressure acting upon another diaphragm which operates the oil supply valve.

Abstract: 1,224,882. Yeast &c. BRITISH PETROLEUM CO. Ltd. June 5, 1968 [July 19, 1967], No.33088/67. Heading C6F. A micro-organism capable of growth on a hydrocarbon is cultivated in the presence of a feedstock which consists of or contains a hydrocarbon and on which the micro-organism is capable of growth, in the presence of an aqueous nutrient medium and in the presence of a gas containing free oxygen and thereafter part of the aqueous medium is separated, the remaining product (or part thereof) comprising the micro-organism in admixture with at least part of the residual hydrocarbon and at least part of the residual nutrient medium is treated with a surface active agent having the formula:- where n is an integer from 11 to 14, m is from 4 to 12 and X is sodium or potassium, and the mixture so obtained is subjected to a separation treatment for the recovery of a fraction in which hydrocarbon predominates and a fraction consisting of or containing a mixture of micro-organism and water. The aqueous medium separated off may be replaced with fresh water to reconstitute the original mixture. The surface active agent is added in proportions within the range 0À02-0À5%, based on the weight of the mixture of micro-organism, aqueous nutrient medium and hydrocarbon. The surface agent is exemplified by an oxyethylenated lauric alcohol sulphate having on average 7 ethylene oxide groups per molecule and a sulphur content of 1.4% by weight. The recovered fraction in which hydrocarbons predominate, containing aqueous medium held in emulsion, may be treated to separate the surface active agent, as follows: (1) with a compound containing a metal ion which forms a water insoluble salt with the surface active agent e. g. calcium or barium hydroxides or carbonates, or salts of zinc and heavy metals; (2) with a mineral acid e.g. HC1 or H 2  SO 4 , under conditions such that the surface active agent is hydrolysed; (3) by cooling to a temperature in the range-10 degrees to +10 C.; or (4) with a solvent e.g. 15-25% by weight of isopropanol. Examples are directed to the cultivativation of Candida tropicalis upon a gas obtained from Middle-East crude petroleum and to the recovery of the product yeast.
